Question, with so many major orgs using it, are there no plans for manual status? The one thing I miss vis-a-vis teams is the ability to manually set myself away, appear offline, busy etc.

Matrix shows me as active (green dot) when I have the client open but there's no way to override that. At least none that I found. I'm a bit surprised all these big governmental clients didn't ask for such a feature :)

There's a big gap between lots of orgs using it, and lots of orgs paying for development of it. That said, BWI in Germany is currently funding custom status so it should be coming soon :)
